P1014 Exhaust Camshaft Position Actuator Park Position Bank 2

P1014 Exhaust Camshaft Position Actuator Park Position Bank 2 is a diagnostic trouble code that indicates the Engine Control Module (ECM) has detected that the exhaust camshaft position actuator on Bank 2 has failed to return to or remain in its specified park position.

Modern engines equipped with Variable Valve Timing (VVT) use camshaft actuators to continuously adjust valve timing for improved performance, fuel economy, and emissions. When the engine is shut off or operating under certain conditions, the exhaust camshaft actuator is expected to return to a default mechanical position known as the park position.

If the ECM determines that the actuator is stuck, moves incorrectly, or cannot reach the expected park position, it stores the P1014 fault code and may illuminate the Check Engine Light.

This fault is commonly associated with VVT actuator problems, oil control valve faults, engine oil issues, timing component wear, or electrical problems affecting the actuator control system.

What Does P1014 Exhaust Camshaft Position Actuator Park Position Bank 2 Mean?

Variable Valve Timing systems continuously change camshaft timing while the engine is running.

The exhaust camshaft actuator changes camshaft position using engine oil pressure under the control of the ECM.

The ECM monitors:

• Desired camshaft position

• Actual camshaft position

• Actuator movement

• Oil control valve operation

• Camshaft position sensor signals

The actuator also has a default mechanical position called the park position.

When P1014 is stored, the ECM has determined that the actuator on Bank 2 cannot properly return to or remain in this position.

Possible causes include:

• Sticking camshaft actuator

• Faulty oil control valve

• Low oil pressure

• Dirty engine oil

• Timing chain wear

• Camshaft sensor problems

What Is Bank 2?

Bank 2 refers to the side of the engine that does not contain cylinder number one.

On V6, V8, V10, and V12 engines:

• Bank 1 contains cylinder number one.

• Bank 2 is the opposite cylinder bank.

Inline engines generally have only one cylinder bank and typically do not use Bank 2 terminology.

What Does the Exhaust Camshaft Actuator Do?

The exhaust camshaft actuator changes exhaust valve timing according to engine operating conditions.

Its functions include:

• Improving engine performance

• Increasing fuel efficiency

• Reducing exhaust emissions

• Improving idle quality

• Optimizing engine torque

The actuator operates using hydraulic oil pressure controlled by the oil control valve.

When operating correctly, the actuator smoothly advances or retards exhaust camshaft timing.

Symptoms of P1014

Symptoms may vary depending on how severely the actuator is affected.

Check Engine Light

The most common symptom is the illumination of the Check Engine Light.

Reduced Engine Performance

Possible performance problems include:

• Reduced power

• Poor acceleration

• Sluggish throttle response

Rough Idle

Incorrect exhaust valve timing may cause:

• Rough idle

• Engine vibration

• Unstable idle speed

Engine Hesitation

Drivers may notice:

• Hesitation during acceleration

• Uneven power delivery

• Delayed throttle response

Increased Fuel Consumption

Improper valve timing may reduce combustion efficiency.

Hard Starting

Some vehicles may experience:

• Extended cranking

• Difficult cold starts

• Rough startup

Engine Noise

Mechanical timing problems may produce:

• Timing chain noise

• Rattling sounds

• Clicking noises near the valve cover

Reduced Fuel Economy

Improper exhaust camshaft timing may increase fuel consumption.

Common Causes of P1014

Several mechanical and electrical issues can trigger this code.

Faulty Exhaust Camshaft Actuator

The actuator itself may fail due to:

• Internal wear

• Mechanical sticking

• Hydraulic failure

• Locking pin malfunction

A sticking actuator may not return to the correct park position.

Faulty Oil Control Valve

The oil control valve regulates oil flow to the actuator.

Possible failures include:

• Internal sticking

• Electrical failure

• Restricted oil passages

• Slow operation

Dirty or Incorrect Engine Oil

The VVT system depends on clean engine oil.

Possible oil-related problems include:

• Dirty oil

• Low oil level

• Incorrect oil viscosity

• Oil sludge

Contaminated oil can prevent proper actuator movement.

Low Engine Oil Pressure

Insufficient oil pressure can prevent the actuator from operating correctly.

Possible causes:

• Worn oil pump

• Internal engine wear

• Oil leaks

• Low oil level

Timing Chain Wear

Timing chain problems may include:

• Chain stretch

• Worn guides

• Weak tensioner

• Incorrect camshaft timing

These problems can affect actuator position.

Faulty Camshaft Position Sensor

Incorrect camshaft position readings may cause the ECM to believe the actuator is in the wrong position.

Wiring and Connector Problems

Electrical issues may include:

• Damaged wiring

• Corrosion

• Loose connectors

• Short circuits

ECM Problems

Although uncommon, an ECM fault may affect actuator control or monitoring.

How Is P1014 Diagnosed?

Proper diagnosis requires evaluating both the VVT system and engine timing components.

Check for Additional Trouble Codes

Technicians should scan for related codes involving:

• Camshaft position sensors

• Oil control valves

• Variable valve timing

• Engine timing

Additional codes often help identify the root cause.

Monitor Live Camshaft Data

A scan tool can compare:

• Desired camshaft angle

• Actual camshaft angle

• Actuator response

Large differences may indicate a mechanical or hydraulic problem.

Inspect Engine Oil

Technicians should verify:

• Correct oil level

• Oil condition

• Correct oil viscosity

Poor oil quality is a common cause of VVT problems.

Inspect the Oil Control Valve

The oil control valve should be checked for:

• Electrical operation

• Mechanical sticking

• Oil contamination

Inspect the Camshaft Actuator

The actuator should be checked for:

• Mechanical movement

• Locking mechanism operation

• Internal wear

Inspect Timing Components

If necessary, technicians may inspect:

• Timing chain

• Chain guides

• Chain tensioner

• Camshaft timing marks

How Is P1014 Fixed?

The repair depends on the cause of the actuator park position fault.

Replace the Exhaust Camshaft Actuator

If the actuator is mechanically damaged or sticking, replacement may be required.

Replace the Oil Control Valve

A faulty VVT oil control valve should be replaced.

Perform an Engine Oil Service

If oil contamination is causing poor actuator movement:

• Replace engine oil

• Replace oil filter

• Use the correct oil specification

Repair Wiring Problems

Possible repairs include:

• Repair damaged wiring

• Replace damaged connectors

• Clean corroded terminals

Repair Timing Components

If timing chain wear is present, repairs may include:

• Timing chain replacement

• Guide replacement

• Tensioner replacement

Repair Oil Pressure Problems

If oil pressure is below specification, the lubrication system should be repaired.

After repairs:

1. Clear the fault code.

2. Start the engine.

3. Monitor camshaft position data.

4. Perform a road test.

5. Confirm the code does not return.

Can You Drive With P1014?

A vehicle with P1014 may continue running, but the issue should be repaired as soon as possible.

Possible consequences include:

• Reduced engine performance

• Increased fuel consumption

• Rough operation

• Timing-related engine damage

• Additional VVT system failures

Driving for long periods with an active VVT fault is not recommended.

Is P1014 a Serious Code?

P1014 is generally considered a moderate to serious engine timing fault.

If the problem is caused by dirty oil or a faulty oil control valve, repairs are often straightforward.

However, if timing chain wear or actuator damage is ignored, more extensive engine repairs may become necessary.

How to Prevent P1014

Regular maintenance helps prevent VVT system problems.

Use the Correct Engine Oil

Always use the oil grade recommended by the manufacturer.

Change Engine Oil on Schedule

Clean oil helps prevent:

• Sludge buildup

• Oil passage restrictions

• Actuator sticking

Monitor Oil Level

Maintain the proper oil level to ensure adequate hydraulic pressure.

Repair Check Engine Lights Promptly

Early diagnosis helps prevent minor VVT faults from developing into major engine timing problems.

Inspect Timing Components

Vehicles with high mileage should have timing components inspected according to manufacturer recommendations.
